ALBION K. WASHBURN, OF BRIDGEWATER, MASSACHUSETTS.

SOLE-LEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 596,292, dated December28, 1897.

Application filed January 30, 1897. Serial No. 621,330. (N0 model.)

To on whom it may concern.-

Be it known that I, ALBIONIK. WASHBURN, of Bridgewater, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulImprovement in Sole-Leveling Machines, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates particularly to an attachment to the jack of asole-leveling machine; and it consists in combining with the jack aswinging frame holding a toe-guard, said swinging frame being adapted tohold the guard firmly in place during the time that the sole-levelin gwork is being done and then to swing away from the toe of the shoe, soas to admit of taking off the shoe and of putting another on. Thismechanism is illustrated in the accompanying drawings, in which- Figure1 is a side view showing the jack of a sole-leveling machine with mytoe-guard device attached. Fig. 2 is an end elevation of the same.

In the drawings, A represents the base of the jack, and B a standard, towhich the-shank O of an iron last or shoe-support L is held by aclamping-piece C and clamp-screws 0*, as shown. To complete theshoe-support L, an adjustable part L (see Fig. 1) is used. This part isconnected to a lever N, which is pivoted at N, and is provided with anadjusting and clamping device of ordinary construction.

The above-mentioned parts need not be more fully described for thereason that they are old and of well-known construction.

The new part relates to the frame for holding the toe-guard R,'andconsists of the following-described parts: A plate D, havingdownwardly-projecting arms D D is pivoted on the pins P P, so that itcan tip laterally, as indicated by the dotted lines in Fig. 2. To thisplate D an upright arm E is attached by a clamping-piece E, held by theclamp-screw E By this construction the upright arm E is free .to be set011 any part of the plate D and securely fastened. This adjustment ofthe upright arm E is required in order to adapt the guard R to act fordifferent-sized shoes. At the top of the upright arm E a guard R isattached. This guard may be of rubber or of any suitable yieldingsubstance that will receive the leveling-roller and not injure it, theposition of the guard in relation to the toe of the shoe being such thatthe roller in passing from the sole of the shoe to the guard, or viceversa, cannot injure the tip end of the toe by crushingit down inleaving or by bruising it in returning.

WVhen the leveling process is not going on and when it is desired to puta shoe onto the last or to remove it, then the lever M is allowed toraise up. This will cause the spring S and rod H to be forced upward,and, acting through the arm II, will swing the plate D and the uprightarm E over to the position shown by dotted lines in Fig. 2, leaving thelast L free from any obstruction, so that the operator may put on ortake off a boot or shoe. The lever M is so balanced and controlled thatit always comes to its highest position unless forced down by theoperator.

To use my device, the operator simply takes his foot from the lever M.This allows the upright arm E and the guard R to fall back into theposition represented by dotted lines in Fig. 2. Now the operator canplace the boot or shoe in position on the last L, and having secured itthereon by the aid of the lever N in the usual manner he presses thelever M down. This, acting through the spring S,

rod H, and arm H, will bring the upright arm E and guard R to its normalposition, the guard B being about on a level or in the same plane withthe sole of the shoe. Now the machine may be started and the work ofleveling the sole performed in perfect safety.

I claim- In a sole-leveling machine, a fixed last or shoe-support, atoe-guard support, adjustable on a line parallel to the long axis of thelast, a toe-guard attached to said support; a frame tilting in adirection lateral to'the said long axis of the last, independent of thelast or shoe-support and adapted to hold the said toe-guard support; andmechanism by which said tilting frame is operated whereby the ALBION K.WASHBURN.
